I would run a compression test to see exactly where your compression pressures stand. Lets talk Farmall's M's H's etc etc,,,,,

If your tractor has 0-100 psi at cranking speed, you can run 1 gallon of E85 to 4 gallons of regular pump fuel, and still notice a difference,, at that mix, it will start and run just like it alawys had,,, What you will see is the manifold flange, where the carb bolts on the manifold, will be avout 25 degrees cooler than what gas would be alone,,,, E85 is a cold fuel when it mixes with air,, it has a tremendous cooling effect,,, like Nitrous,, just not as cold,, but it almost as cold as LP when it mixes with the incoming air. You make power from that cooling effect, that does happen to stay cooler than most conventional fuels.
If, your tractors engine has 130-150 psi,,, 2 gallons of E85 to 3 gallons of pump gas will be fine,, More E85 you can mix, and burn the more power it can make.

I'll tell you right now,,, E85 is more of a lower rpm fuel than a high rpm fuel,,, The tractor engines seem to respond better to E85 due to having all the time in the world to make a good mix in the intake, where a faster rpm engine, has to get in, burn up fast and get out ready for the next charge to burn,,,,, E85 likes to hang around in the cyl,,, slow burn,, colder temps in the cyl.

Pure staight E85 can run a Farmall stroker engine at 300psi of compression at cranking speed and not detonate, or preignite!! Wonderful stuff that whiskey is,,,, HAHAHA!!

I know I have ran a H farmall with a big stroker, at 290psi, at 50% 93 pump gas, and E85 and make more power, run better than any race fuel out there!! Never detonated, preignited, nothing! Never damaged parts, It hasnt eaten away the pistons, or showed no sign of anything being out of whack.

Hope some of this Info helps clear up the mystery,,, If you tell me how much compression, cubic inch of your farmall tractor, I can tell you exactly how to make your farmall tractor run on E85. ChadS
